The Chimney Rock Interpretive Association (CRIA) is proud to announce its upcoming Lecture Series, featuring “The Chaco Phenomenon,” a captivating three-part program that explores the rise and fall, influence, and legacy of the Ancestral Puebloan Chaco Culture and its enduring connection to Chimney Rock National Monument. The series will take place over three consecutive Fridays in August at 6:00pm, at the United Methodist Church Fellowship Hall. Doors will open at 5:45pm. Each lecture will feature a distinguished expert in Southwestern archaeology and anthropology.
Admission is free. This series offers a rare opportunity to hear from some of the region’s most respected voices in Southwestern archaeology and to deepen your understanding of one of North America’s most fascinating ancient cultures.
Lecture 1: Chaco Canyon – Its Origins, People, and History
Friday, August 15 at 6:00pm
Presented by G.B. Cornucopia, retired National Park Service archaeologist and long-time interpretive ranger at Chaco Canyon, this talk will trace the roots of the Chacoan culture, from its early inhabitants and monumental architecture to its peak influence and eventual decline. Cornucopia, a pioneer in Chaco’s astronomy programs, brings decades of field experience and a passion for ancient skywatching traditions.
Lecture 2: The Chaco Culture – Its Influence, Outliers, and Decline
Friday, August 22 at 6:00pm
Join Tori Myers, Executive Director of the Salmon Ruins Museum, as she delves into the geographic and cultural reach of the Chacoan world. Myers will discuss the intricate network of outlier communities such as Chimney Rock, as well as the social, religious, and linguistic ties that bound them to Chaco Canyon. Her work emphasizes both scientific archaeology and the storytelling power of artifacts and cultural memory.
Lecture 3: The Chimney Rock Great House and Chaco Regional System
Friday, August 29 at 6:00pm
Presented by Dr. Susan Ryan, Executive Vice President of the Research Institute at the Crow Canyon Archaeological Center, this lecture focuses on the Chimney Rock Pueblo itself — its community and the role it played within the Chacoan regional system. Dr. Ryan’s presentation will highlight the broader implications of archaeological study in understanding community development and cultural identities.
The lectures are free. Donations are welcome. Canned goods for the church’s food pantry are greatly appreciated.
